It surprises me the way our society has changed the view we have of nature, other species and other animals. I assume it must be very difficult for some of us to look among other nature creatures and realise they have more similarities with us than differences. But still we have always had this feeling of being superior. Our outstanding intelligence, our feelings, our social capabilities seamed unique capacities of human beings. For the last decades science has proved this “uniqueness” was not as unique as we thought.

As the reader probably knows dolphins are marine mammals with an extreme intelligence that has been proven to be at least similar to ours. When talking about dolphins we should probably talk about Diana Reiss, professor of psychology at Hunter College. She has mainly researched on understanding cognition and communication in dolphins and other cetaceans in addition she has researched self-recognition patterns of such animals as well as in elephants. Professor Reiss is also the author of several books likeThe Dolphin in the Mirror: Exploring Dolphin Minds, Saving Dolphin Lives…

Dolphins are extreme capable echo-locators. They are capable of creating noises with different frequencies and develop what is called sonograms, which are basically graphic images based on noise, so you could say, that dolphins see “acoustically” what they hear. (More on echolocation here) This is made in a way that they create a photographic image from what they hear, so if you show a cup to a dolphin inside the water, he will be able to point that cup when he sees it with it’s eyes out of the water. Professor Reiss has studied how this accurate perception of the world models the way dolphins socialise and emphasise with others. There are many different tales throughout history that claims different human’s have been helped by dolphins. Diana Reiss keeps collection of a lot of them:

I read on the news the other day about a retired policeman in New Zealand, her dog felt from a cliff into the ocean. So, she jumped into the water to rescue her dog, but she ended fighting in the waves and she was going to drawn. She explained, how then a group of dolphins came to save her and pushed her and her dog back to the rocks at the beach. (From Redes para la ciencia episode:155)

Dolphins and humans shared common ancestor lived about 90 million years ago, and even though our genetic differences are big, some cognitive capabilities look similar in both species. This phenomenon is known as parallel convergence in evolutional biology. Diana Reiss believes dolphin’s intelligence is some point between chimpanzee’s and ours. Dolphins can create objects with their bodies such as bubbles in the water to play with. Every group uses different techniques to create them. The same issue happens with the sounds they make that could resemble the existence of different cultures. Dolphins are even able to use tools such as sea sponges when searching the seabed in order not to damage their nose. The dolphins language is really complex, you can identify their emotional state and have specific sounds for every individual being basic for their social activity. Not enough with that they have also grammatical patterns such as the way they put the words in the sentence is not the same: Put the ring in the basket and Put the basket in the ring, even when both sentences have the same words. Dolphins recognise themselves when looking in the mirror which means they have conscious and empathy, being able to recognise when somebody is in danger and needs help such as the photographer hardy jones.

It is really clear for me that dolphins resemble much of what I intend to understand as an intelligent creature and I am pretty sure much more mammals are able to make quite good models of the world they live in, as well as having similar social capacities. Hope you think of this when you watch another dolphin perform any trick inside a closed pool…

While I was reading the robots chapter I began to ponder about some of the ideas mentioned. I understand that some scientists argue whether our brain is the most complicated system ever made by nature and this is why it will be impossible to be replicated. I would not say that this is untrue, but I think that we trend to be really egocentric when we think about our own specie capabilities. Although our brain can be an incredible tool there are still many other brains that nature has developed and that are capable to deal in an amazingway with a hostile environment although we do not exactly know today what is their level of consciousness when doing so.

It is mentioned that robots are capable of achieving goals but without any real understanding about the pursued goal. A robot might be able to fix a car’s tire, but without any understanding of what a tire or a pump really is. Is this true? Do we understand what a tire or a pump is? Even when dealing with this simple objects human definitions will surely vary from one to another. So what knowledge should the robot have in order to really understand his goal purpose? What is a tire? what materials is made of? Should it understand his use? Or might it be the fact that tires are usually round? .. I think human beings trend to get lost sometimes in the sea of their own abstract ideas and concepts and that this should not be the purpose of a common robot. I think our sometimes egocentric vanity does not help us realise human beings are not perfect although evolution implies exactly that capacities are not at their best and can always get better. I think a good example of this is the square game where robots trend to be pretty better than us although it implies a little bit of thinking and very little operations.

If you don’t know the answer already try thinking about it, it will give you a better idea of what I am trying to explain here.

Human brain is not so good sometimes when we have to think out of the box.

So I think we need to create new robotic systems so that they understand the processes they will be dealing with. Robots that can understand their own plant system. System failures usually happen due to fails in the control system more than in the system itself, control engineers usually fix this problems adjusting the control system parameters. Therefore, complex systems should be able to understand their own system plant and be able to understand their controllers in order to adjust their parameters so that they can act consequently if any problem arises. We need to create robots that can understand their interactions with the world and their capacity to pursue effectively their goals in the way that is better suited for “surviving” in the environment they have to deal with.

Michio Kaku explains:

“Animals can be conscious , but in a different conscious level as the human being. We should try to classify the different types and levels of consciousness before debating about any philosophical issues of it. In time robots might develop a silicon consciousness (…) erasing the difference between semantics and syntax’s and their answers would be indistinguishable from human’s. This way the question of whether they actually or not understand the question would be basically irrelevant.

This past week a new interesting project about the human brain was approved by the European Commission. This project has been selected with an european flagship FET (Future and emerging technologies) which means it’s set to receive a billion euros and also to be funded as FET “flagships” over 10 years through its research and innovation funding programmes.

Modern neuroscience has been enormously productive but unsystematic. The data it produces describes different levels of biological organisation, in different areas of the brain in different species, at different stages of development. Today we urgently need to integrate this data, to show how the parts fit together in a single multi-level system.The “Human Brain Project” will create the world’s largest experimental facility for developing the most detailed model of the brain, for studying how the human brain works and ultimately to develop personalised treatment of neurological and related diseases. This research lays the scientific and technical foundations for medical progress that has the potential to will dramatically improve the quality of life for millions of Europeans.

Develop first draft models and prototype technologies, demonstrating how the platforms can be used to produce results with immediate value for basic neuroscience, medicine and computing technology.

From this goals they generate other subgoals that the project wants to achieve, I want to remark the next ones:

Understanding the relationships between brain structure and function, integrate the principles of cognition, that from a technological perspective it would give developers the tools they need to develop robots with the potential to achieve human-like capabilities, impossible to realise in systems that do not have a brain-like controller. The Human Brain Project work in neuromorphic computing and neurorobotics would open the road for the development of compact low-power systems with the long-term potential to achieve brain-like intelligence.

I want to end this post with the next paragraph quoted from the International Technology Roadmap for Semiconductors,2011.

The appeal of neuromorphic architectures lies in i) their potential to achieve (human-like) intelligence based on unreliable devices typically found in neuronal tissue, ii) their strategies to deal with anomalies, emphasising not only tolerance to noise and faults, but also the active exploitation of noise to increase the effectiveness of operations, and iii) their potential for low-power operation. Traditional von Neumann machines are less suitable with regard to item i), since for this type of tasks they require a machine complexity ( the number of gates and computational power), that tends to increase exponentially with the complexity of the environment (the size of the input). Neuromorphic systems, on the other hand, exhibit a more gradual increase of their machine complexity with respect to the environmental complexity. Therefore, at the level of human-like computing tasks, neuromorphic machines have the potential to be superior to von Neumann machines

I don’t know if you have already heard about the human echolocation phenomenom. For those of you who haven’t, this post’s title probably has left you a bit astonished, but human echolocation in an ability that has been known for at least the 1950s.

We could say that human echolocation its a process similar, in a way, to the one used by bats, dolphins and some whales to recognise their surroundings and location. Equally to the way a sonar works using sound echoes to recognise objects.What we normally see is just the light reflection on an objects surface, that gives us the trace, form and size of what we are looking at. Evolution has developed eyes as light “sensors” and eyes plus their brain connections provides us with a really powerful tool to cope with the environment, walk around, be able to recognise objects, enabling easy space positioning. In contrast we could define human echolocation as the ability of humans to detect objects in the environment by sensing echoes from those objects by actively creating sounds, for example by making clicking noises or tapping a cane. People trained to orientate with echolocation are able to interpret the sound waves reflected by nearby objects, accurately identifying their location and size, so this ability is used by some blind people to navigate within their environment using their auditory senses rather than their visual ones.

Vision and hearing are closely related in that they can process reflected waves of energy. Both systems can extract a great deal of information about the environment by interpreting the complex patterns of the reflected energy they receive. Sound carries information about the nature, arrangement of objects and other environmental features. Giving information about location, dimension and density of the object the sound reflects from.

It has been recently shown that blind echolocator’s experts use what is normally the “visual” part of their brain to process the echoes, primary visual cortex. Most interestingly, the brain areas that process auditory information were not activated in this subjects, in the performed experiments, more than in other normal subjects. Which gives the idea that blind echolocator’s experts sense the world similarly the way other people do, but using a completely different strategy for information gathering.

When talking about human echolocator’s, we must mention Daniel Kish, born in 1966 in Montebello, California. Blind since he was 13 months old, he is an expert in human echolocation and president of World Access for the Blind, a non-profit founded in 2000 which helps people with all forms of blindness. Kish and his Organisation have taught echolocation to at least 500 blind children around the world inspiring other scientists to study human echolocation. Other remarkable human echolocator’s are Lucas Murray from Poole, Dorset. Who was born blind and was one of the first british people to learn to visualise his surroundings using human echolocation, taught by Daniel Kish and Ben Underwood (1992-2009)

The human brain continuous to embrace incredible features, evolution was the great tool that boosted its creation and guides its capabilities. Do we use the hole capabilities of our brain? The most reasonable option is that we must use most of them. Brains are expensive organs in terms of energy costs and I believe it is reasonable that our evolution would’t have allowed those nonsense great energy expenses. So I believe that if we weren’t using our hole brain, the brain would had probably shrunken. There is an example of this. When talking about some type of birds, while mating season, the male which is the one who searches for food, has to remember where the best food is and where the nest is in order to return to it with the food, so it’s brain is bigger than the female one, which does not have to gather this knowledge. But is incredible to realise, that when not on mating season, when the birds do not have to remember where is easy to find lots of food and how to return to the nest, the male brain shrinks. In order to lose less energy, and when back on mating season the male’s brain expands again.

Do we use the brain the only way it can be used? I believe this is a totally different question, I believe perception is the key fact, usually missing when trying to understand cognition. Human echolocators do not “hear” the echoes as we would do it, they really” see” the sound reflected from the objects, I mean, their brain constructs the image the same way we do, but using sound instead of light. Obtaining at the end very similar results from evolution’s point of view which is, at the end, helping the entity surviving in the environment. So I believe that only time will tell if there are totally different ways of using our brain, but we must be always really open minded for any new ways of thinking that will surely arise in the future.

At last I would like to mention Kevin Warwik, born the 9th of february in 1954 in Coventry, Uk. Is a British scientist and professor of cybernetics at the University of Reading. He is well know for his studies on direct interfaces between computer systems and the human nervous system. Has done interesting researches in echolocation’s field. Kevin Warwik is an incredible scientist, related with cognition and artificial intelligence and deserves a future entrance in this blog, so for now I will only talk about his particular conception with respect to artificial intelligence, he claims that we have many limits, such as our sensorimotor abilities, that we can overcome with machines. In his own words:

“There is no way I want to stay a mere human”

I would like to add to this blog entrance this documentary on Ben Underwood (1992-2009) and the human echolocation phenomenon. Not only for the scientific purposes but also for telling his beautiful biography of overcoming and struggle. When this was recorded he was still alive. Hope you enjoy it.

Eduard Punset is a multidisciplinary researcher well know in Spain because since 1996 he has directed and presented “Redes” a scientific Tv program based around interviews with leading scientists.He is also professor of science, technology and society at the Faculty of Economics of the Chemical Institute of Sarrià.

I wanted to translate, his new year’s decalogue from his blog, which I found really inspiring and share it with all non spanish readers.

1- Since the last century life expectancy rises two years and half every decade.

2- Thanks to 1, today’s people are less obsessed about life after death, they are much worried about noting there really is life before death.

3- We should devote less time in healing politics, instead prevention politics should be our priority. Basically this means that we should practice daily sports, watch our diet, know how to enjoy what we already have and don’t cry only for what we lack.

4- Social and emotional learning must be added immediately to the educational system. For this we must prepare educators to understand positive and negative emotions so they can help us manage them correctly.

5- We must demarcate negative competences, which prevents us from getting a job, from positive competences, which can really boost our possibilities of getting a good one. Among the first ones, we must avoid emotional ignorance (lets see if we finally understand the meaning of despising others) and among the second ones we must understand that happiness resides inside happiness waiting room.

6- We must note intuition and subconscious importance in contraposition to rational conscious thoughts. I will never forget that woman crying that stopped me in the street to thank me for giving her confidence on her intuition again. While others had tried to prevent her from trusting it her whole live.

7- Understanding real happiness dimensions has been the greatest 20th century conquest. We have understood that is not necessarily the money the one which confers that happiness. When you live under the subsistence level, money is happiness, but exceeded that level control over our own live is the dimension more correlated with happiness. Having the impression that what you do matters for some reason.

8- The beauty that a many people search for, is really pain absence. But many people are willing to cope with pain without any evident reason in order to get their desired job or fulfilling their dreams . Exercising and working without suffering is understanding pain to gain control.

9- The herd, when crossing a river or climbing a mountain, always relies on youth. The main next century’s problem will not be wealth distribution, but work distribution. Schools and new enterprises should have already started the study and application of this principle. State and other social institutions and enterprises must open their doors to the marginalised youth.

10- Please, its time to resign dogmatism and accept as a daily practice the uncertainty principle. When something is intuited must be checked and if it works must be applied till someone comes and proves the contrary. Newton convinced the world that Time was exactly the same for all, was absolute. After, Einstein said it was relative, dependant on the mass and velocity. End dogmatists that much suffering imposed on those who doubted!

I hope you have found the reading interesting. I apologise for the translations accuracy, I’m not a translator. I tried to write it accurately and I hope I have been able to make his points clear.

Most of you, have probably heard about Dr. Marvin Minsky , one of the most influential authorities inside Cognitive Science. Co-founder of the Massachusetts Institute of Technologies AI laboratory. In my opinion, he is one of the most intelligent thinker I have ever heard.

This is a talk in 2009 in which Marvin Minsky tries to explain why we need intelligent machines and what we can expect from them. His research group has been working on cognitive architectures trying to develop better intelligent machines using AI. Although it is a few years old, it is one of the most interesting and funny talks I have experienced so far, and I was able to find it recently on iTunes.

Education is no good, unless you teach them to question it. And it is not popular.

Sarcastic Marvin Minsky begins talking about why we need intelligent machines. He claims that if we knew how to build a machine that could think more or less the same way that people can, we should surely understand its behaviour, being capable in the future to know how to fix and replace all of this machines parts and equally all of the the brain’s ones to. In his own words “Immortality would be easy to obtain” This way we would be able to make backup copies of our brains and download and upload them into this machines.

One thing he points out and which I can not do anything but totally agree, is that in the Universities, high-schools and collages, people are developing again and again the same kinds of robots. In his own words” You can learn a lot from doing this, like that if you step on connectors …. they brake.” People should be working on something more useful. For example, robot-soccer might be beautiful to watch for a few minutes but it is useless and has not much value for humanity. Why not try to research on robots that do something more useful?

The best is the enemy of the good. Don’t spend a lot of time trying to find the best way. Find six good ways, it will take you half the time and your machine will be six times better when the environment changes

Dr. Minsky remarks that the ambiguity of language is really a useful tool we use to learn, as it is possible to obtain a better result at the end by misunderstanding what you where initially told. As when somebody realises a different idea from something you have read before, but you didn’t thought of that at that moment. But now, that you have been told about it, the idea seems really plausible. It is clear that people learn in various ways, and that people develop different ways to learn. I agree with Dr. Minsky, that we should focus our efforts not on education as we are doing it right now, but more on understanding ways to learn and improving old commonly used techniques as reinforcement by reward. Instead, we should better ask ourselves why some kids learn more from the same experience than others and improve our ways of teaching how to learn.

If you can tell yourself what you did, you might misunderstand it and do something better next time

Talking about AI, Dr. Minsky gives a brief history description through the first AI to symbolic calculation. How this development has provided powerful tools for mathematic integration using Matlab or Mathematica. But right now, computers can only solve logical formulated problems and can not operate by analogy. He explains that there are not enough people researching on example based reasoning, which he believes will be the future of computer programming and instead that to much effort and money is spent on neural networks, statistical learning, genetic algorithms…which will inevitably pass away and become obsolete.

Thousands of people are doing something because they see thousands of other people doing it, so therefore it must be good. I know only about twenty or thirty people in the hole world who are working on how to get computers to do anything like ordinary common sense reasoning and thats where I think, the future lays.

Through the whole lecture Dr. Marvin gives his point of view on a bunch of different topics and problems of society, science, education, politics, even sports, in a very sarcastic way. Although I do not agree with all of them, I have found them really funny and makes the lecture easy to listen and understand.

On a menu, when you have a choice I always order chicken this days, because your children won’t have any chicken to order

I came across the other day a really interesting project named FIONA. Maybe some of you have heard of it. You can check out its cool web here.

Project Fiona or The community for the creation of the artificial mind, aims as their developers explain, to be an online platform to create the next generation of virtual avatars. Many blog and internet users knows what an avatar is, basically we could define it as a personalized graphic file or rendering that represents a computer user.

By what The community calls sparks which trends to be something like little applications that can contribute to the platform uploading their killer feature, a specific behavior, an amazing character or the best of their knowledge in a topic.

With this type of technology we can expect in the near future a new generation of avatars which might be able to export your own ideas, knowledge even your personality in ways only science fiction visionaries dreamt about. Virtual teachers could attend to virtual classes, this technology could change the way we understand meetings, they could be used as interfaces for waiters, sellers and I can imagine more and more other possibilities…

I have not been able to test the platform, neither the interface or the sparks programming, I hope to have some time in the near future to test it (it looks it has a nice and friendly interface to work with, see second video) so I’m not able to judge right now if FIONA’s avatars can really manage complex tasks and develop real, clear conversations and interactions, but I believe that this project can be a great platform to test if this are real actual possibilities or only steps towards future technologies, time will tell.

You are able to find a few tutorials for beginners on their website and youtube like this one:

Divide and conquer is a common technique used by strategists in many fields. Comprehension usually involves understanding the details and it means usually better adaptation to the “environment”. I’ll try to explain myself with an example: When trying to face a problem in any science without understanding the main physics involving all the procedure. You might have encountered, you are able to resolve that specific problem or even a similar one but, when the “environment changes”, by this I mean that the problem differs from the initial one in a simpler way, but in a way that is such that your abstract idea of the physics confuses you and makes you solve it the wrong way. But instead anyone who already understands that physic fact will easily evolve its previous answer the right way.

Imagine you memorized the math table for two, then you will be able to accomplish any multiplication relying number 2. When asked to multiply 3*2 you are able to answer easily, but if the question is 3*3 you wont. But instead if you learn the math table for two, understanding that 2*5 is five times two (2+2+2+2+2) you will be able to answer 3*8 immediately. And you might be able to infer that 8/2 equals 4 because there are two fours “inside” an eight (4*2) (4+4). By mathematical terms you could say, this situation is more adapted to a changeable mathematical environment.

For many years control engineers have tried to reduced complex, abstract processes to simpler and more achievable ones, which interact with each other to develop the more complex process which englobes the simpler ones. This way using feed-back loops engineers are able to automate a control system towards its goal.

As robots usually are really complex systems, they are very difficult to control. Interactions between its components can easily lead to malfunctions that can make impossible for the system to achieve it´s desired goal. Now, new simpler, adaptable robots are being researched by Amsterdam engineers working inside an European project, a great idea to solve complex difficulties, making robots which will be able to interact with each other in incredible ways (show by the video)

I imagine future robotics, as multiple interactive robots specialised in little tasks working in groups, being capable of sharing information and developing solutions as a group. Understanding perception will be very important for this robots, in order to be able to communicate to each other its own situation and the final group’s goal, in which I believe cognitive science’s and the study of social interactions will clearly help the research of new cognitive architectures, which will allows us in the near future to master new control techniques for this new multiple robot platforms.

Listening to Dharmendra Modha manager from IBM Cognitive Computing Systems, makes me wonder how far we are from really interacting with cognitive computers. IBM has been able to simulate about 500 billion neurons, 100 trillion synapses all running on a collection of ninety-six of the world’s fastest computers this year. The project code name is Compass which goal is to be able to simulate a brain of a macaque monkey making of this project, the most ambitious attempted to this day.

Compass is part of long-standing effort known as neuromorphic engineering, an approach to build computers developed by the engineer Carver Mead. The premise behind Mead’s approach is that brains and computers are fundamentally different, and the best way to build smart machines is to build computers that work more like brains. Especially when relating with common sense interpretation, understanding language and sensations.

Whereas traditional computers largely work executing serial tasks (one step after another) and using classical logic (if-while and-or), neuromorphic systems work in parallel, and draw their inspiration as much as possible from the human brain describing functionalities in terms of neurones, dendrites and axons.

If Moore’s law continues to be fulfilled and the number of transistors on integrated circuits continue to double every two years. What would we be able to accomplish in a few years? A growing crew of neuroscientists and engineers believe that the key on building better autonomous machines that emulate brain capacities is by implementing them neurones by neurones. I humbly that there is to much research still to be done on neurones connections and that implementing just neurone by neurone knowing how they are connected isn’t enough to deduce the complete behaviour.

We should better emphasise on understanding how the brain and nervous system works in other simpler species otherwise we could be just trying to mimic something we really don’t understand, time will tell.

The human brain has awesome powers of sensation, perception, cognition, emotion, action and interaction. It can bring together multiple sensory modalities, while consuming less power than a light ball and occupying less volume than a two litter bottle of soda

I remember a few years ago I came across with a documentary called something like “Incredible minds“. It was about a man called Daniel Tammet which was an autistic savant, able to work out great numerical problems in an incredible way. I was really impressed, not only of what the documentary showed he was capable of, but more about the way he explained how he did it. He claimed he had never seen numbers the way, “others” did. Instead he was synaesthetic with numbers, he felt sensations related with them. And he claimed that when he was resolving a numerical problem he was really abstracting a form out of a mental image that the numbers involved sketched in his mind.

This made me wonder if the way maths were thought, were not the ideal way they should be. Or maybe, I understood maths in a way differently from the way others did. And when I say maths I mean any other subject or concept that might be studied. We mostly learn the most simple concepts by patters that are repeated constantly again and again and finally become kind of subconscious. Think, for example on math tables, or first vocabulary lessons in most foreign language classes you might have attended. Maybe, understanding the basics by repetition is not the most effective way to learn, even when infants seem to learn this concepts fast, I believe we don’t exactly make them know in a meaningful way.

Understanding that your own-percepcion models any concept you might learn, it would be really interesting finding other ways of learning common concepts that could be a lot more powerful than the way it is done today. Researching on mental syndromes, synaesthetics and the way they understand the environment could help us open our eyes.

I came across, recently with this TED talk from Daniel Tammet that might be well self-explanatory about this ideas:
